MEDIA RELEASE | Installation of water filters not a DIY job

New Zealand homeowners looking to take the extra precaution in controlling the purity of the water entering their homes by installing water filters are being warned that this is not a DIY job.
Generally, the installation of water filters is considered to be sanitary plumbing and must be carried out by an authorised tradesperson.

This includes the range of filters from those supplying water for the whole building to those with a single tap installed under the kitchen sink.

Exceptions to this would be filters that have a push on connection fitted to the outlet of a kitchen tap or a stand-alone tank/bottle type filter.

PGDB Chief Executive, Martin Sawyers said; “We’re reminding homeowners not to risk their family’s health and safety or their insurance by installing water filters themselves, or by hiring unauthorised tradespeople to undertake the work.”

He added: “Tradespeople carrying out restricted plumbing work must be able to produce their licence card if asked – and consumers should ask to sight it. This provides assurance that the work is being legally carried out by an authorised and competent tradesperson, who is currently licensed by the PGDB.”

If a homeowner is unsure if the installation of a specific type of water filter falls into the restricted work category – they can give the Board’s hotline a call on 0800 743 262 for clarification.
